IMPROVEMENT IN VULCANIZING-CHAMBERS FOR USE IN THE MANUFACTURE OF ARTICLES 0F lNDlA- RUBBER.

Specification forming part of Letters Patent No; 215,984, dated August 26, 1879; application filed June 25, 1879.

To all whom it may concern and State of New Jersey, have invented certain new-and useful Improvements in Vulcanizing-Ohambers,of which theifollowing is a specification.

This inventionrelates to vulcanizing-chambers for use in the manufacture of articles of india-rubber. V

It consists in a chamber furnished with a series of pipes unconnected with and isolated] from each other, though extending from a steam-receptacle common to all, wherebythe liability of leakage is lessened, and'facility afforded for repairing or replacing any of the pipes without detriment to the operation of the others. L

It also consists in a chamber furnished with series of pipes connected to receptacles, so that the several series and their receptacles are independent of the others, are supplied with and exhausted of steamindependently of the others, and may be controlled and repaired independently thereof.

It also consists in details hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a central vertical section of a vulcanizing-chamber embodying my invention, and Fig. 2 is a horizontal sectioniof the same.

Similar letters of reference designate corresponding parts in both figures.

A designates a vulcanizing-chamber, which may be built of brick, wood, or other material, in theordinary or any other suitable manner, and provided with a doorway, X, one or more, and tracks A,ifor carriages containing articles to be vulcanized.

B designates series of pipes extending laterally from a receptacle, B, composed of an inner and outer compartments, and arranged in proximity to the side walls of the chamber A. The several pipes are isolated from and independent of each other, and are furnished at the outer ends with caps B In these pipes are smaller pipes B open at the inner ends, receiving steam from the inner compartment of the receptacle B, and extending therefrom to near the outer ends of the pipes B. At

, .the outer end they are closed by caps B pro- Be it known that I, WILLIAM E. KELLY, of. New Brunswick, in ,thecounty of Middlesex vided with an opening much smaller than their interiors.

Steam circulates-from the inner compartment of the receptacle B through the pipes B and back through the pipes B into the outer compartment of the receptacle B again. The caps B on the outer ends of the pipesB owing to the smallness of the openings therein, serve to check the flow of steam, so that it will not flow mainly through the pipes adjacent to its source, but will flow uniformly, or nearly so, through the whole of the series.

. The inner compartment of the receptacle B is supplied with steam by a pipe, B provided with a stop-cock, B andleading to its upper part from a drum, D, or a steam-generator arranged outside the chamber'A, and it is exhausted of steam by means of a pipe, B,leading from the lower part of the receptacle, and

provided with a stop-cock, B".

. It is obvious that any one of a series of pipes isolated and independent of each other, as are those described, can be removed, and the hole in its receptacle plugged, so as to permit of the use of the other pipes when necessary, or fitted with a new pipe; and, furthermore, that pipes so combined, being destitute of connections, will be less liable to become disarranged and leaky than if connected to form a coil or circuit.

O designates a series of pipes furnished with caps 0 containing smaller pipes 0 fitted with perforated caps 0 and connected with a receptacle, C. This receptacle comprises inner and outer compartments, is supplied with steam by a pipe, 0 provided with a stop-cock, G communicating with the drumD or a steamgenerator, and is exhausted of steam by a pipe, C provided with a stop-cock, 0'. All these parts are similar to analogous parts before described, save that the pipes G and G excock, E leading from the drurnllora steam; generatonaiid E designates a pipe provided with a stop-cock, E whereby steam, is ex hausted from the receptacle. All these parts are similar to corresponding parts before de-- scribed, and are in proximity to the front of the chamber A, below the'doorway. The pipes here extend from one side of the receptacle E only. I p p 7 Gdesignates pipes fitted with caps G extending in horizontal rows from opposite sides of a horizontally-arranged receptacle, G, and. containing smaller pipes G fitted with perforated caps G". This receptacle is supplied with steam by a pipe, G leading from-the drum D or a steam-generator, and provided with a stop-cock, G and it is exhausted of steam by a pipe, G provided with a stopcock, G". All these parts are like those corre-j sponding to them, and before described, and, are arranged below the, tracks A in the chain-i her A, and near the floor of the latter. It will be seen that any of these series of; .pipes B, C, E, and G may be controlled byl .means of the supply-pipes B, G, E, and G .with their stop-cocks 13 0 E ,'and G and the exhaust-pipes B, O, E, and G with the stop-cocks B", 0 E and G, independently of each other series, and hence that the heat: may be regulated at different parts of the chamber, as may be desirable, and thatif either series of said pipes needs repairs the others are not necessarily rendered inoperative.

It is obvious that, in lieu of the pipes con-i taining smaller pipes for securing circulation of steam, pipes containing longitudinal parti tions extending to within a short distancefrom their outer ends may be used.

The steam-receptacles B, O, E, and G and .the pipes communicating with them may be arranged in various positions other than those Y illustrated and described with good results.

. tially as specified, whereby liability to leakage isilessened, and any pipe of any series may be repaired or replaced by another without in terfering with the others of the series.

2. Achamber furnished with series of pipes unconnected with and independent from each other, extending from a receptacle, and containing within them smaller supply-pipes furnished with caps having small openings, so as to check the flow of steam through them, substantially as and for the purpose specified.

3. A chamber furnished with series of pipes connected to receptacles supplied with steam by pipes leading from a drum or steam-generator, and provided with stop-cocks, and exhausted of steam by other pipes, also provided f with stop-cocks, substantially as specified,

whereby heat. maybe directed to different parts of the chamber, and they may be repaired in- I WILLIAM E. KELLY.
